Abstract

Background: Porphyromonas gingivalis bacteria are found in dental plaques and have the ability to form biofilms. Biofilms are collections of bacterial cells, which are tightly attached to a surface covered by an extracellular polymer matrix released by the bacteria. Periodontitis therapy generally uses tetracycline antibiotics which if used long-term can cause resistance. Chitosan Rajungan crab extract (Portunus pelagicus) has antimicrobial potential which can be used as an alternative therapy. Objective: To determine the antibacterial power of Rajungan crab chitosan extract (Portunus pelagicus) in various concentrations of Porphyromonas gingivalis bacterial biofilms. Method: This research was true experimental laboratorist. This study used Rajungan crab chitosan extract (Portunus pelagicus) to Porphyromonas gingivalis biofilm tested by the test method biofilm. Divided into 5 groups, where each group consisted of 4 samples. The control group consisted of: K- (negative control group), K + (positive control group / tetracycline group), and 3 treatment groups, namely P1 (0.25% Rajungan crab chitosan), P2 (0.5% Rajungan crab chitosan) , P3 (1% Rajungan crab chitosan). Antibacterial power was determined by the value of Optical density in the ELISA Reader. Data analysis using One Way ANOVA followed by LSD test. Result: There were significant differences (p <0.05) seen from the percentage of biofilm inhibition in the negative control group for all groups, the positive control group for the crab crab chitosan extract concentrations of 0.25% and 0.5%. Conclusion: The chitosan crab chitosan extract (Portunus pelagicus) with 1% concentration has the greatest antibacterial effect on the Porphyromonas gingivalis biofilm.

Abstract

Background: Diabetes mellitus (DM) is a metabolic disorders characterized by hyperglycemia caused by oxidative stress. Porphyromonas gingivalis (P.g) is a periodontopathogen caused periodontitis exacerbate blood glucose levels (BGL). Hyperbaric oxygen therapy (HBOT) combined with stichopus hermanii (SH) has a role as an antioxidant and antibacterial agent. Purpopse: To analysis effect of HBOT, SH powder and combination of both to the level of blood glucose diabetic Wistar rat induced P.g. Materials and Methods: This study was pre-test-post-test control group design, using 20 male Wistar rat were divided into 5 groups, Group1 (STZ), Group2 (STZ+P.g), Group3 (STZ+P.g+HBOT), Group4 (STZ+P.g+SH powder), Group5 (STZ+P.g+HBO+SH). STZ induction intravenous for 4 days in a row. P.g. induction was exposure 3 times for 4 days. After therapy (7 days), sample blood tail vein of rat were taken for measure BGL by glucometer. Result: Level of blood glucose K1(280.25±88.786)mg/dl, K2(372.25±135.662)mg/dl, K3(249.50±96.652)mg/dl, K4(172.00±82.077)mg/dl, K5(104.75±38.257)mg/dl. Conclusion: Induction of STZ increased the BGL but induction of P.g. cannot exacerbate BGL . HBOT combined with SH powder can reduce BGL in STZ and P.g. induction group.
